Arope is 225 centimeters long. you need the rope to be meters long. how many centimeters should you cut off?

Solve the triangle. a = 21°, c = 105°, c = 5

Look at the figure below: triangle abc is a right triangle with angle abc equal to 90 degrees. the length of ac is 5 units and the length of ab is 4 units. d is a point above c. triangle adc is a right triangle with angle dac equal to 90 degrees and dc parallel to ab. what is the length, in units, of segment cd?

Corresponding angles are a. always b. sometimes c. never congruent
